Therefore, the long\u2010term outcome, patellar redislocation rate, and functional outcome after conservative versus operative procedures were investigated in a prospective randomized study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Initially, 36 patients with acute primary patellar dislocation were prospectively randomized to conservative (<jats:italic>n<\/jats:italic> = 20) versus operative procedures (<jats:italic>n<\/jats:italic> = 16) and 30 of them (83 %), 15\/20 with conservative and 15\/16 with operative procedures, were reached for a follow\u2010up interview 6 years after primary procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Baseline and clinical parameters were similar in the two groups. The prevalence of patellar redislocation rate at 3 and 6 years after primary procedure was higher in the conservative group (7\/20, 35 %, 3 years and 11\/15, 73 %, 6 years) versus in the operative group (0\/16, 0 %, 3 years and 5\/15, 33 %, 6 years) (<jats:italic>p<\/jats:italic> = 0.02). The knee function was slightly better 6 years after primary treatment in the operative group than in the conservative group. Most patients in both groups had excellent or good knee function at 6\u2010year follow\u2010up, but four patients (4\/15, 27 %) in conservative group and two patients (2\/15, 13 %) in operative group had poor knee function at 6\u2010year follow\u2010up. Four patients in conservative group (4\/15, 27 %) and two patients in the operative group (2\/15, 13 %) were unsatisfied with the procedure at 6\u2010year follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In conclusion, the results suggest that both conservative and operative procedures are feasible options for treatment of acute primary patellar dislocation in adolescents. A new finding with clinical relevance in the present work is a significantly higher redislocation rate in conservative group compared to operative group after 6\u2010year follow\u2010up in acute primary patellar dislocation in adolescents.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>II.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-014-3271-3","type":"journal-article","created":{"date-parts":[[2014,9,5]],"date-time":"2014-09-05T05:43:17Z","timestamp":1409895797000},"page":"6-11","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":51,"title":["Six\u2010year outcome after non\u2010surgical versus surgical treatment of acute primary patellar dislocation in adolescents: a prospective randomized trial"],"prefix":"10.1002","volume":"24","author":[{"given":"Gideon","family":"Regalado","sequence":"first","affiliation":[{"name":"Department of Surgery South Carelia Hospital Lappeenranta Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hannu","family":"Lintula","sequence":"additional","affiliation":[{"name":"School of Medicine University of Eastern Finland Kuopio Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hannu","family":"Kokki","sequence":"additional","affiliation":[{"name":"School of Medicine University of Eastern Finland Kuopio Finland"},{"name":"Department of Anestesiology and Intensive Care Kuopio University Hospital Kuopio Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heikki","family":"Kr\u00f6ger","sequence":"additional","affiliation":[{"name":"School of Medicine University of Eastern Finland Kuopio Finland"},{"name":"Department of Orthopedics Kuopio University Hospital Kuopio Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Urho","family":"V\u00e4\u00e4t\u00e4inen","sequence":"additional","affiliation":[{"name":"School of Medicine University of Eastern Finland Kuopio Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matti","family":"Eskelinen","sequence":"additional","affiliation":[{"name":"School of Medicine University of Eastern Finland Kuopio Finland"},{"name":"Department of Surgery Kuopio University Hospital (KYS) P.O.
